      This chair has so many settings, it allows you to fine tune your massage to exsctly the area you want, or has several general massages already programmed in. Excellent quality, works perfectly took one hour to assemble. Does everything its advertised to do.

    • Love this chair!
      Verified Purchase

      I really shopped it out before picking this Osaki 4000 massage chair. I had someone come set it up for me. It is Amazing! Everyone in my house was lined up to use it. I liked the appearance, the sturdiness, all the massage choices, the zero gravity and heated option. This is a great machine at a good price. Buy one!

    • The massage chair I ever wanted

      I purchased this particular massage chair after I got married recently. We were thinking of purchasing one even before, but we took some time to research in order to find the best one for us. We are pretty satisfied with what we got now because the massage itself is quite deep. I wish it was a little bit stronger, but overall we love it. I especially love the air pillow because I can feel the extra air bags, and it helps me relax. My husband loves when he reclines all the way since there is two stage of zero gravity. It hits more spots once he reclines especially his back area. I have some shoulder pains as well, and we didn't know how to get that point. When we called the customer service, they were very kind. Two people helped us by giving us very clear instructions and sending us a video link on Youtube. You should definitely check that out because it really helped us understand the chair better. The massage is not too strong as it hurts the bones yet it's strong enough to take care of muscle sore. We would surely recommend to our friends and family. This is such an amazing investment.

      Love this chair, the only thing I was not happy with is the fact that you have to put it together by yourself.

    • Impossible to assemble
      Verified Purchase

      This Chair arrived pretty fast, was excited to get it, and tried to assemble it right away. The instructions are confusing , and areas that need assembling are hard to reach under the chair. Impossible to put bolts on screw , because there is a metal bar in the way that cannot be moved. spoke to customer service about returning it, they told me it was buyers remorse , because the chair couldn't be put together, and I was responsible for return shipping.I called back later and spoke to someone else, and am in the process of trying to get this chair picked up and returned.

    • I already have an OS-4000

      I have already purchase an Osaki 4000 for myself and place it in the living room. No I plan on getting a 2nd one for the Master Bedroom. Call me crazy, but I am spoiled and need extra attention before I go to bed and watch a game or two. I give 2 thumbs up and a 10 on the board.
